' To all whom it may concerafl Be it known that l, Vannn'rinn DAHL, acitizen of the United States, and a resident of the city of New York,oorough of Brooklyn, in the county of Kings and State of New York, haveiriventeda new and ,lnr proved Hose-Coupling, of which the fol lowing isa full, clear, and exact description. I

Reference is to be had to the accompany-- ing drawings forming axpart ofthis spec fication, in which similar characters of reference indicatecorresponding parts in all the views, and in which ,Fignre l is a planview; Fig. is a longitudinal section through the cc er of the device;Fig. 8 is a plan view oi the coupling sleeve; Fig. dis a transversesection through the coupling sleeve; F 5 is an end. view showing thehinged relation of the members of the couplingsleeve; and Fig. 6 is alon gitudinal section through the center of the coupling sleeve.

lteferring more particularly rate parts,'1 and 2 indicate suita lecoupling members, to which secured in any "Well-known i'nanner, as bymeans of Wire-Wrappings 3 an liosepi ies and 6.

in the form sho iathe dra'a'ngs, the coupling men'iber;v and. 2dstl'erent diameters, and there is therefore provided reducing member 7,interposed between i and separa. from them by a suitable nt substance,such as rubber packing rings 8 and 9. All of the parts i, 2 and 7 havecylindrical flanges 10, 11, and 13 thereon, to engage the rings 8 and 9.Each of these flanges 10, 11, 12 and 13 is also provided with undercutgrooves, which are adapted to be engaged by suitable cylindricalundercut flanges l4, 15, 16 and 17, which extend inwardly from one ormore sleeves 18 and 19, whereby said meu'ibers are secured together. Thesleeves 18 and 19 are preferably formed in two parts 20 and 21, whichare pivoted together in any suit able manner, as by means of hinges 22and 23.

While the device has been shown as attached to hose members of diiferentsizes, with an intermediate reducing member, it may be also attached tohose-attaching mem-- bers of the same size, in which case, theintermediate reducing member is unnecessary,

and only a single sleeve need be used to se cure the members together. v

The coupling members and the reducing member have been shown telescopingone in the other, but this is not absolutely necessary, as they mayterminate at the beginning of the rings 8 and 9.

The method of attaching the separate members Will be readily understoodfrom the above description. The two adjacent a ainst the resilientaction of the spring member between them, and the two parts 20 and 21 ofthe sleeve, separated, and the undercut-flanges snapped intothe undercutves on the separate members. The members are then. allowed to separateunder the action of the spring means between them, thus forcing theflanges and grooves to' gather, forming an intimate locking joint.

While the members have been described as having a groove, and the sleeveas having the flange, it may be said that either or both have aflange-and-groove connection.

Having thus described my invention, .1 claim as new and desire to secureby Letters Patentri 1, In a hose coupling, the combination with couplingmembers, of a reducing memberintermediate said coupling members,undercut flanges-on all of said members, a plurality of sleeves havingengaging undercut flanges thereon adapted to secure said memberstogether, and resilient means be- Ween said members adapted to forcesaid ilanges into interlocking engagement. a 2. In a hose coupling, thecombination with attaching members, of a reducing memher locatedintermediate said attaching member, rubber washers between said members,cylindrical undercut flanges on said members, and a plurality of sleevesfor inclosing said flanges and having undercut flanges thereon adaptedto engage said flanges on said members, said sleeves comprising twoparts alined together.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
